The four towns were in the section of Hampden County that was briefly under a tornado warning Monday afternoon, after a sever thunder storm with strong winds rolled through toward Worcester.

In Berkshire County, the majority of customers without power are in the town of Lenox which is reporting 2,271 customers affected. Stockbridge had another 71 customers with no power.

The National Grid was also reporting 103 customers without power in Erving, and another 69 in Wendell in Franklin County.

Western Massachusetts Electric Co. also reported scattered outages throughout Western Massachusetts. The highest concentrations were 63 in Pittsfield and 67 in Greenfield.

Most of Western Massachusetts remained under a severe-thunderstorm watch, meaning conditions were right to make such storms possible. The watch is in effect until 8 p.m.
Much of Franklin County was also under a flood advisory through 6:15 p.m. The high amount of rain in the last two days has increased likelihood that streams and some streets could be flooded.
